In this “Ask Me Anything” (AMA)
episode, Peter and Bob dive deep into cancer screening, including
why it’s important, what you need to know about a test, and Peter’s
approach with patients. They specifically discuss various screening
methods, explain important terms like sensitivity and specificity,
and how layering and stacking different tests in tandem can improve
predictive values. They conclude with a discussion on one of the
more exciting screening tools, diffusion-weighted MRI, and how it’s
changing the cancer screening landscape.
